- Initializes a new platform plugin that ships out of the box w/ x-pack
- Contains a very basic front-end that shows AS engines, error states, or a Setup Guide
- Contains a very basic server that remotely calls the AS internal engines API and returns results

- URL casing appears to be snake_casing, but kibana.json casing appears to be camelCase

- I haven't had much success in surfacing a SVG file via a server-side endpoint/URL, but then I realized EuiIcon supports passing in a ReactElement directly. Woo!

- instead of crashing folks on load

- per product decision, URL should be enterprise_search/app_search and Workplace Search should also eventually live here
- reorganize folder structure in anticipation for another workplace_search plugin/codebase living alongside app_search
- rename app.tsx/main.tsx to a standard top-level index.tsx (which will contain top-level routes/state)
- rename AS->ES files/vars where applicable
- TODO: React Router

- remove showSetupGuide flag
- add a new shared helper component for combining EuiButton/EuiLink with React Router behavior (https://github.com/elastic/eui/blob/master/wiki/react-router.md#react-router-51)

- create shared helper (WS will presumably also want this) for generating EUI breadcrumb objects with React Router links+click behavior
- create React component that calls chrome.setBreadcrumbs on page mount
- clean up type definitions - move app-wide props to IAppSearchProps and update most pages/views to simply import it instead of calling their own definitions

* Added unit test for server

* PR Feedback

- rather them passing them around verbosely as props, the components that need them should be able to call the useContext hook

+ Remove IAppSearchProps in favor of IKibanaContext

+ Also rename `appSearchUrl` to `enterpriseSearchUrl`, since this context will contained shared/Kibana-wide values/actions useful to both AS and WS

* application.test.ts

* Added Unit Test for EngineOverviewHeader

* Added Unit Test for generate_breadcrumbs

* Added Unit Test for set_breadcrumb.tsx

* Added a unit test for link_events

- Also changed link_events.tsx to link_events.ts since it's just TS, no
React
- Modified letBrowserHandleEvent so it will still return a false
boolean when target is blank

* Betterize these tests

* Set up Telemetry usageCollection, savedObjects, route, & shared helper

- The Kibana UsageCollection plugin handles collecting our telemetry UI data (views, clicks, errors, etc.) and pushing it to elastic's telemetry servers
- That data is stored in incremented in Kibana's savedObjects lib/plugin (as well as mapped)
- When an end-user hits a certain view or action, the shared helper will ping the app search telemetry route which increments the savedObject store

* Update client-side views/links to new shared telemetry helper

* Write tests for new telemetry files

* Write tests for React Router+EUI helper components

* Update generate_breadcrumbs test

- add test suite for generateBreadcrumb() itself (in order to cover a missing branch)
- minor lint fixes
- remove unnecessary import from set_breadcrumbs test

* Write test for get_username util

+ update test to return a more consistent falsey value (null)

* Add test for SetupGuide

* [Refactor] Pull out various Kibana context mocks into separate files

- I'm creating a reusable useContext mock for shallow()ed enzyme components
+ add more documentation comments + examples

* Write tests for empty state components

+ test new usecontext shallow mock

* Empty state components: Add extra getUserName branch test

* Write test for app search index/routes

* Write tests for engine overview table

+ fix bonus bug

* Write Engine Overview tests

+ Update EngineOverview logic to account for issues found during tests :)
  - Move http to async/await syntax instead of promise syntax (works better with existing HttpServiceMock jest.fn()s)
  - hasValidData wasn't strict enough in type checking/object nest checking and was causing the app itself to crash (no bueno)

* Refactor EngineOverviewHeader test to use shallow + to full coverage

- missed adding this test during telemetry work
- switching to shallow and beforeAll reduces the test time from 5s to 4s!

* [Refactor] Pull out React Router history mocks into a test util helper

+ minor refactors/updates

* Add small tests to increase branch coverage

- mostly testing fallbacks or removing fallbacks in favor of strict type interface
- these are slightly obsessive so I'd also be fine ditching them if they aren't terribly valuable

* Fix optional chaining TODO

- turns out my local Prettier wasn't up to date, completely my bad

* Fix constants TODO

- adds a common folder/architecture for others to use in the future

* Remove TODO for eslint-disable-line and specify lint rule being skipped

- hopefully that's OK for review, I can't think of any other way to sanely do this without re-architecting the entire file or DDoSing our API

* Add server-side logging to route dependencies

+ add basic example of error catching/logging to Telemetry route
+ [extra] refactor mockResponseFactory name to something slightly easier to read

* Move more Engines Overview API logic/logging to server-side

- handle data validation in the server-side
- wrap server-side API in a try/catch to account for fetch issues
- more correctly return 2xx/4xx statuses and more correctly deal with those responses in the front-end
- Add server info/error/debug logs (addresses TODO)
- Update tests + minor refactors/cleanup
    - remove expectResponseToBe200With helper (since we're now returning multiple response types) and instead make mockResponse var name more readable
    - one-line header auth
    - update tests with example error logs
    - update schema validation for `type` to be an enum of `indexed`/`meta` (more accurately reflecting API)

… name to simpler 'app_search'

- since their mapping already nests under 'kibana.plugins'
- note: I left the savedObjects name with the '_telemetry' suffix, as there very well may be a use case for top-level generic 'app_search' saved objects

- to better follow/use jest setups and for .mock.ts suffixes

* Licensing plugin setup

* Add LicensingContext setup

* Update EngineOverview to not hit meta engines API on platinum license

* Add Jest test helpers for future shallow/context use

* Update new nav categories to add Enterprise Search + update plugin to use new category

- per @johnbarrierwilson and Matt Riley, Enterprise Search should be under Kibana and above Observability
- Run `node scripts/check_published_api_changes.js --accept` since this new category affects public API

* [URL UPDATE] Change '/app/enterprise_search/app_search' to '/app/app_search'

- This needs to be done because App Search and Workplace search *have* to be registered as separate plugins to have 2 distinct nav links
- Currently Kibana doesn't support nested app names (see: elastic#59190) but potentially will in the future

- To support this change, we need to update applications/index.tsx to NOT handle '/app/enterprise_search' level routing, but instead accept an async imported app component (e.g. AppSearch, WorkplaceSearch).
- AppSearch should now treat its router as root '/' instead of '/app_search'

- (Addl) Per Josh Dover's recommendation, switch to `<Router history={params.history}>` from `<BrowserRouter basename={params.appBasePath}>` since they're deprecating appBasePath

* Update breadcrumbs helper to account for new URLs

- Remove path for Enterprise Search breadcrumb, since '/app/enterprise_search' will not link anywhere meaningful for the foreseeable future, so the Enterprise Search root should not go anywhere
- Update App Search helper to go to root path, per new React Router setup

Test changes:
- Mock custom basepath for App Search tests
- Swap enterpriseSearchBreadcrumbs and appSearchBreadcrumbs test order (since the latter overrides the default mock)

Now that elastic#66455 has been merged in 🎉

* Add i18n provider and formatted/i18n translated messages

* Update tests to account for new I18nProvider context + FormattedMessage components

- Add new mountWithContext helper that provides all contexts+providers used in top-level app
- Add new shallowWithIntl helper for shallow() components that dive into FormattedMessage

* Format i18n dates and numbers

+ update some mock tests to not throw react-intl invalid date messages

* Fix Prettier linting issues

* Escape App Search API endpoint URLs

- per PR feedback
- querystring should automatically encodeURIComponent / escape query param strings

* Update server plugin.ts to use getStartServices() rather than storing local references from start()

- Per feedback: https://github.com/elastic/kibana/blob/master/src/core/CONVENTIONS.md#applications

- Note: savedObjects.registerType needs to be outside of getStartServices, or an error is thrown

- Side update to registerTelemetryUsageCollector to simplify args

- Update/fix tests to account for changes

* Wired up basics for E2E testing

* Added version with App Search

* Updated naming

* Switched configuration around

* Added concept of 'fixtures'

* Figured out how to log in as the enterprise_search user

* Refactored to use an App Search service

* PR feedback - updated README

* Additional lint fixes

Co-authored-by: Constance <constancecchen@users.noreply.github.com>

* Add plugin README and CODEOWNERS

* Fix public mocks

* Fix empty states types

* Fix engine table component errors

* Fix engine overview component errors

* Fix setup guide component errors

- SetBreadcrumbs will be fixed in a separate commit

* Fix App Search index errors

* Fix engine overview header component errors

* Fix applications context index errors

* Fix kibana breadcrumb helper errors

* Fix license helper errors

* ❗ Refactor React Router EUI link/button helpers
- in order to fix typescript errors

- this changes the component logic significantly to a react render prop, so that the Link and Button components can have different types - however, end behavior should still remain the same

* Fix telemetry helper errors

* Minor unused var cleanup in plugin files

* Fix telemetry collector/savedobjects errors

* Fix MockRouter type errors and add IRouteDependencies export

- routes will use IRouteDependencies in the next few commits

* Fix engines route errors

* Fix telemetry route errors

* Remove any type from source code

- thanks to Scotty for the inspiration

* Add eslint rules for Enterprise Search plugin

- Add checks for type any, but only on non-test files
- Disable react-hooks/exhaustive-deps, since we're already disabling it in a few files and other plugins also have it turned off

* Cover uncovered lines in engines_table and telemetry tests

- Prefer setting CSS class overrides on individual EUI components, not on a top-level page

+ Change CSS class casing from kebab-case to camelCase to better match EUI/Kibana

+ Remove unnecessary .euiPageContentHeader margin-bottom override by changing the panelPaddingSize of euiPageContent

+ Decrease engine overview table padding on mobile

* Move getUserName helper to shared

- in preparation for Workplace Search plugin also using this helper

* Move Setup Guide layout to a shared component

* Setup Guide: add extra props for standard/native auth links

Note: It's possible this commit may be unnecessary if we can publish shared Enterprise Search security mode docs

- saved objects: removing indexing per elastic#43673
- add schema and generate json per elastic#64942
- move definitions over to collectors since saved objects is mostly empty at this point, and schema throws an error when it imports an obj instead of being defined inline
- istanbul ignore saved_objects file since it doesn't have anything meaningful to test but was affecting code coverage

…arch (#19)

* Set up new server security dependency and configs

* Set up access capabilities

* Set up checkAccess helper/caller

* Remove NoUserState component from the public UI

- Since this is now being handled by checkAccess / normal users should never see the plugin at all if they don't have an account/access, the component is no longer needed

* Update server routes to account for new changes

- Remove login redirect catch from routes, since the access helper should now handle that for most users by disabling the plugin (superusers will see a generic cannot connect/error screen)
- Refactor out new config values to a shared mock

* Refactor Enterprise Search http call to hit/return new internal API endpoint

+ pull out the http call to a separate library for upcoming public URL work (so that other files can call it directly as well)

* [Discussion] Increase timeout but add another warning timeout for slow servers

- per recommendation/convo with Brandon

* Register feature control

* Remove no_as_account from UI telemetry

- since we're no longer tracking that in the UI

* Address PR feedback - isSuperUser check

* Add server-side public URL route

- Per feedback from Kibana platform team, it's not possible to pass info from server/ to public/ without a HTTP call :[

* Update MockRouter for routes without any payload/params

* Add client-side helper for calling the new public URL API

+ API seems to return a URL a trailing slash, which we need to omit

* Update public/plugin.ts to check and set a public URL

- relies on this.hasCheckedPublicUrl to only make the call once per page load instead of on every page nav

- Split up scenario cases as needed
- Add plugin as an exception alongside ML & Monitoring

- version: kibana
- copy edits
- Sass vars
- code cleanup

…o camelCase

- note: current remainng snake_case exceptions are telemetry keys
- file names and api endpoints are snake_case per conventions

- remove set
- remove unnecessary capabilities registration
- telemetry namespace agnostic

see elastic#66922 (comment)
- add if statement
- pass log dependency around (this is kinda medium, should maybe refactor)
- update tests
- move test file comment to the right file (was meant for telemetry route file)

- Remove unnecessary ServerConfigType
- Remove unnecessary uiCapabilities
- Move registerTelemetryRoute / SavedObjectsServiceStart workaround
- Remove unnecessary license optional chaining

Address type/typos

- I can't even?? I swear charset=utf-8 fixed the same error a few weeks ago

- Fix incorrect navigateToApp slug (hadn't realized this was a URL, not an ID)
- Update without_host_configured tests to run without API key
- Update README

- remove unnecessary authz?
- remove unnecessary content-type json headers
- add loggingSystemMock.collect(mockLogger).error assertion
- reconstrcut new MockRouter on beforeEach for better sandboxing
- fix incorrect describe()s -should be it()
- pull out reusable mockDependencies helper (renamed/extended from mockConfig) for tests that don't particularly use config/log but still want to pass type definitions
- Fix comment copy
